- Which carbon atom is the hemiacetal carbon atom in each of the following structures?arrow_forwardName each of the compounds in Problem 15-106 in the manner described in Section 15-11.arrow_forwardFor each structure in Problem 18-103, identify the configuration at the acetal carbon atom as or .arrow_forward
- What is the IUPAC name of this structurearrow_forwardTell whether each of the following substituents on a steroid is axial or equatorial. (A substituent that is up is on the top face of the molecule as drawn, and a substituent that is down is on the bottom face.) (a) Substituent up at C3 (b) Substituent down at C7 (c) Substituent down at C11arrow_forward15-11 In what way are constitutional isomers different from stereoisomers? In what way are they the same?arrow_forward
- 16-54 Several poisonous plants, including Atropa belladonna, contain the alkaloid atropine. The name “belladonna” (which means “beautiful lady”) probably comes from the fact that Roman women used extracts from this plant to make themselves more attractive. Atropine is widely used by ophthal mologists and optometrists to dilate the pupils for eye examination. Classify the amino group in atropine as primary, secondary, or tertiary. Locate all stereocenters in atropine. Account for the fact that atropine is almost insoluble in water (1 g in 455 mL of cold water) but atropine hydrogen sulfate is very soluble (1 g in 5 mL of cold water). Account for the fact that a dilute aqueous solution of atropine is basic (pH approximately 10.0).arrow_forwardIUPAC name ofarrow_forwardPredict the MAJOR product(s) of each reaction or sequence of reactions. Show stereochemistry where applicable and draw out ALL stereoisomers that are formed as MAJOR products. For those with more than one reaction, show ONLY the final product(s) after all steps listed are performed (intermediate products will not be graded). Assume all reagents are in excess.arrow_forward
